Abstract: A coating composition comprising a thermoplastic acrylic polymer in a solution wherein the polymeric solution, devoid of pigment, has a surface tension of less than 25.2 dynes per centimeter at room temperature is particularly useful as an automotive top coating. The coating compositions, when sprayed onto substrates, exhibit increased efficiency of paint deposited per unit of paint sprayed.

Abstract: FLUORINATED ALIPHATIC LONG CHAIN ADDITION POLYMERS COMPRISED OF AT LEAST ONE MONOMER HAVING AT LEAST ONE FLUORINE ATOM ATTACHED TO A CHAIN CARBON ATOM ARE USED IN VARIOUS ENVIRONMENTS FOR THEIR ABILITY TO REFLECT A HIGH PERCENTAGE OF INCIDENT LIGHT HAVING A WAVE LENGTH IN THE 2400 TO 8000 ANGSTROM REGION . THESE REFLECTANCE POLYMERS MAY BE IN PRESSED POWDER FORM OR IN FILM FORM AND THUS ARE ESPECIALLY APPLICABLE AS REFLECTANE STANDARDS AND REFLECTANE COATINGS PARTICULARLY IN LIGHT INTEGRATING SPHERES OF SPECTROPHOTOMERTERS.
